Q1. Why are so many tests performed on the oil? Are they all necessary?
A1. We believe that all tests are a necessity, and not a luxury. Some oil analysis companies offer a reduced service at a reduced cost, offering customers a choice of the level of service desired. Even if only three per cent of all engines analysed show a dangerous level of water contamination, it is not worth bypassing this test and risking equipment worth hundreds of thousands of Rands to save a few Rand on oil analysis. It is this philosophy that enables WearCheck to offer customers true peace of mind.
Q2. What is PQ?
A2. The PQ (Particle Quantifier) gives a bulk iron reading irrespective of the particle size. It is able to detect particles that are too large for the spectrometer to pick up. The higher the PQ index, the more serious the problem. A high PQ would automatically indicate that a microscopic particle examination must be carried out as an in-depth test to evaluate the severity of the wear problem.
Q3. Do I need oil analysis if my equipment is still covered under warranty?
A3. Yes, because a problem could develop towards the end of the warranty period which could cause a failure outside the warranty. Oil analysis can provide solid evidence for warranty claims. Many major manufacturers such as Caterpillar and Komatsu realise the value of oil analysis and insist that it is conducted during the warranty period.
Q4. If I do field tests on diesel engine oils, do I still need to send the sample for analysis?
A4. Yes, ideally, field screening tests that indicate the presence of fuel dilution or sludging should be done on all samples. The samples still need to be sent for complete analysis to measure the levels of other contaminants and wear metals.
Q5. I am using extended drain interval oil. How do I know if it is really time to change the oil?
A5. Oil analysis enables you to take the guesswork out of when to change your oil.
Q6. How soon after taking a sample should I get it to the lab?
A6. Forward samples immediately to the lab after sampling. Quickly analysing the sample ensures the highest quality and timely decisions. If a severe problem is indicated, a quick response may prevent an imminent failure.
